AbstractHeavy breed day-old chicks fed Isonitrogenous-Isocaloric diets supplemented with 0.0, 2.0 and 4.0% fresh bovine bile liquid, for three weeks. The three types of diets comprised the experimental dietary treatments, from which the effect of including bile liquid in heavy breed chicks diet on their most prominent economical traits were studied. Results showed that the three groups of birds, consumed almost the same amount of feed during the three weeks of experimental period. However, a significant increase in daily growth rate(DGR)occurred as a result of bile liquid in starter diets. The estimated superiority of this traits, DGR, was found to be 10.76% on an average basis, higher than that of the control group. A good reflection of this phenomenon on feed conversion ratio was observed, as birds fed diets contained 2.0 and 4.0% bile liquid surpassed the control group by 8.75 and 10.63%, respectively. Body weights at third week of age were 8.06 and 10.60% heavier for the two treated groups, respectively, than the control one. Results indicate that the nutritive value of starter diets supplemented with bile liquid warrant further investigation based on long term experiments to make a decision in this direction.
